Physics

A black hole formula worked out in the 1970s remains the most concrete clue physicists have about the threads of the space-time fabric.

A mysterious phenomenon known as duality often leads to new discoveries in physics. This time, space-time itself can sometimes be two things at once.

The philosopher Karen Crowther digs into how the space-time fabric could possibly emerge from something non-spatiotemporal.

These three imagined scenarios lead many physicists to doubt that space-time is fundamental.

Until his dying days, the giant of 20th-century physics obsessed over the underpinnings of space and time, and how we can all share the same version of them.

This special issue of Quanta Magazine explores the ultimate scientific quest: the search for the fundamental nature of reality.

Last year, an immense but brief outburst of seismic energy was soon followed by a long hum that made the world ring. Finding its cause took 68 scientists and an assist by the Danish military.

The Industrial Revolution brought us the laws of thermodynamics, and new ideas about work, energy and efficiency. In this episode, co-host Steven Strogatz speaks with theoretical physicist Nicole Yunger Halpern about what these concepts might mean in the age of quantum mechanics.

An ultra-precise measurement of a transition in the hearts of thorium atoms gives physicists a tool to probe the forces that bind the universe.
